The Uruguayan sank his teeth into the defender's arm in the second half of the two sides' 2-2 draw at Anfield, later going on to seal the injury-time equaliser.

The FA confirmed in a statement on its official website that "the incident was not seen by the match officials and has therefore been retrospectively reviewed.

"It is alleged that the conduct of Suarez constitutes violent conduct and it is the FA's contention that the standard punishment of three matches that would otherwise apply is clearly insufficient in these circumstances."

The Liverpool star has until 18.00BST on Tuesday to appeal, with an independent panel to be brought together on Wednesday to hear the charge.
